Title: Fitting device for letter-e-shaped snap ring
Inventor: TANAKA KOICHI
IPC: F16B21/18
Filed: 1989-03-08
Abstract: PURPOSE:To ease the fitting work of a letter-E-shaped snap ring by constituting the device in the title in such a manner that a snap ring supporting member, on which an abutting part of the E-shaped snap ring is formed is fixed, to a main body and the E-shaped snap ring, which is held by projections on both sides, in supported by the abutting part of the snap ring supporting member when a slide base retreats. CONSTITUTION:A pressed surface of a letter-E-shaped snap ring B is abutted on a abutting part 13, and both sides of the E-shaped snap ring B are inserted into both holding projections 23 and 23. Two rows of annular, recessed grooves 28 and 29 are provided around a shaft S, and an E-shaped snap ring C is fitted into the annular groove 28. Meanwhile, an E-shaped snap ring B is fitted into the annular groove 29, with a part P is fitted to the shaft S. To do so, first, the tip of a fitting device A is moved toward the annular groove 29, while it is abutted on the shaft S, then, both the opening part 8 of the E-shaped snap ring B and the recessed surface 18 of a slide base 15 are brought in contact with the peripheral surface of the shaft S, and the E-shaped snap ring B goes into the annular groove 29. Next, if the fitting device A is pushed against the shaft S, only the slide base 15 retreats relatively, overcoming the spring (17) force. Consequently, the E-shaped snap ring B can be fitted into the annular groove 29 as it is.

Title: Heat pipe
Inventor: ISHIKAWA YUUICHI
IPC: C23C22/68
Filed: 1980-04-25
Abstract: PURPOSE:To control the reaction between water and carbon steel by a method wherein a triferric tetroxide film is formed on the internal surface of the heat pipe and an aquaous solution of ethylene diamin tetra-sodium acetate salt is sealed into the heat pipe. CONSTITUTION:In order to form the triferric tetroxide film on the internal surface of the heat pipe, the heat pipe is treated at high temperature after the aquaous solution of ethylene diamin tetra-sodium scetate salt adjusted to a suitable pH is sealed into the heat pipe. The reason why such aquaous solution is sealed into the pipe is that by so doing, the triferric tetroxide film thus formed can regenerate immediately even when the film is destructed due to the influence of heat stress or external stress. The thickness of the film is preferably in the order of 0.05-0.5mm..

Title: Smoothing processor
Inventor: MINAMITANI ISEI
IPC: G06T3/40
Filed: 1985-03-20
Abstract: PURPOSE:To obtain the thick and smooth contours of the oblique lines of mixed patterns with data containing a small number of lines, by deciding the presence or absence of the unit picture elements of the oblique lines according to the enlargement information only when a dot pattern is equal to an enlargement pattern. CONSTITUTION:A picture memory 10 stores a dot pattern including a standard pattern and an enlargement pattern mixed together as well as the enlargement information showing whether the dot pattern is equal to an enlargement pattern for each function block. Based on the enlargement information, a smoothing decoder in a picture display processor 70 decides whether the using unit picture element exists or not at the contact position between enlarged picture elements of the oblique line formed by spot contact between the enlarged picture elements only in case the dot pattern is equal to an enlargement pattern. When the using unit picture element is decided, the unit picture elements are totally displayed. Thus it is possible to display the thick and smooth contours of the oblique lines of mixed patterns with the data containing a small number of lines.

Title: Wire-bonding method
Inventor: TAKAHASHI KOICHI
IPC: H01L21/60
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent bonding defects due to the vibration of a mechanism by executing the operation of a capillary tool drawing an almost arc-like track, at the time of forming a loop by means of controlling the speed patterns of respective X, Y and Z-axes, so that angular velocity on the track in a polar coordinate on time becomes continuous. SOLUTION: Almost cycloid patterns are adopted as the patterns of angular velocity, and speed patterns in which angular velocity is continuous on time are used. Namely, the operation of a capillary tool 13 drawing the almost arc- like track at the time of forming the loop is executed by controlling the velocity patterns of the respective X, Y and Z-axes, so that the angular velocity on the track in the polar coordinate system becomes continuous in time. Consequently, a sudden acceleration change does not appear in the speed patterns of the respective X, Y and Z-axes. Thus, the vibration of the mechanism of a bonding device can be prevented, and a stable loop without bonding defects can be formed.

Title: Direct memory access device
IPC: G06F13/28
Filed: 1992-03-13
Abstract: PURPOSE:To make DMA transfer from a memory to a specific transfer destination device efficient when a series of data are stored in the memory divisionally as plural discontinuous blocks. CONSTITUTION:The blocks of the data 302 stored in the memory are given control information 303. The control information 303 indicates the head address of the block to be read next by DMA. Its head bit 304 is used to discriminate between the data 302 and control information 303. The data are read out of the memory by the DMA according to a DMA transfer command from a CPU and the head address of the block to be read next is decided according to the control information 303. Consequently, the data 302 stored as the discontinuous blocks can be transferred by the DMA with one DMA transfer command generated by the CPU and the frequency of actuation of the DMA decreases, so the DMA transfer efficiency is improved.
